I've replaced all of the glow plugs about a year ago, and replaced the wiring harness under the valve cover as well due to cold start issues. All worked well for a while. Now I'm having cold start issues again.
I checked the ohms on the harness last night, and 3 GP's are showing infinite resistance already.
Question: How long are GP's supposed to last? Is there a preferred brand of GP?

I intend to replace all GP's once again since I'm going to have to dive in there , I will check the connection on the wires just to be sure its connected well at the gp.
Suggestions?

Schultzer you must be a psychic. 7 out of 8 came out fine. The last one, ( drivers side rear one) literally unscrewed and came apart INSIDE of the cylinder. Now Ive got issues. Any chances to fish out the glow plug entrails? Maybe pull the injector and get it out through that access?

Head is off, missing half of Autolite GP located. Autolite sales rep was quite relieved there was no engine damage. Reassembly tomorrow.
My mechanic discovered 2 lots of gp's. one lot was "staked" to prevent them from unscrewing. The other lot was loctited together. The one gp that i had come apart didnt have any loctite on the threads and wasnt staked. Once this was pointed out to the rep he accepted responsibility for repairing it.
Im pretty happy about not having to get stuck with the bill.
Note to self: always always always check with this forum BEFORE replacing any parts on my PSD.
